If you have ever been out running and you felt as if your hip snapped or popped out, it is a case of Snapping hip syndrome. This snapping of the hip usually happens when taking a corner.
Cause of Snapping of hip
The Snapping hip syndrome is because of the repetitive nature of running. This repetitive movement of the hip causes thickening of the tendons in the hip region. It happens after a long training period.
According to Wikipedia Page, this condition is usually curable with appropriate treatment, or sometimes it heals spontaneously. If it is painless, there is little cause for concern.
Therapy for Snapping hip syndrome.
A self-treatment recommended by the U.S. Army for a soft tissue injury of the iliopsoas muscle treatment, like for other soft tissue injuries, is a HI-RICE (Hydration, Ibuprofen, Rest, Ice, Compression, Elevation) regimen lasting for at least 48 to 72 hours after the onset of pain. “Rest” includes such commonsense prescriptions as avoiding running or hiking.
